A Fun Way to Learn About Seed Phrases!

SUPER IMPORTANT WARNING

With a normal "single-sig" wallet, your one seed phrase is the ONLY key to your Bitcoin.

  • → If someone steals it: they take everything forever.
  • → If you lose it or it gets damaged: your Bitcoin is gone forever.

NEVER type your real seed phrase into this game, any app, website, or chat.

The words in this game are real BIP39 seed words from the official list (used here only for practice). They are not your family’s real seed phrase, and you should never type a real wallet seed into any game or website.

That's why Bitcoin Adviser teaches grown-ups something much safer called Collaborative Security using multi-sig.

With Collaborative Security:

  • There are 3 keys (made from seed phrases) instead of just 1
  • You hold one key, and trusted partners hold the other two
  • You need 2 out of 3 keys to move Bitcoin; no one person can take it alone
  • Even if you lose one key, your Bitcoin is still totally safe because you have backups!
